We are already using hexadecimals for pseudo-tty e.g.
...ttyqa, ttyqb, ttyqc...,
I simply can't see any reason why it should be different for reall
serial devices... We support the cyclades multi-serial port cards with
up to 64 ports... 4 cards will give 256 serial ports and personally
I would hate to see the highest port being called tty0255... ;-)
